I'm not sure if this is a problem with the STLs or if it's a problem with Kisslicer, but I'm seeing toolpaths generated that are floating in space outside the part. See this for example:

Maybe a little hard to see, but all those circled areas are floating in space and not part of the object model.
I was able to fix this on some parts by running it through Netfabb cloud, but the Extruder doesn't want to play nice. Could this be something wrong with the object geometry? I've run other objects through Kisslicer and not seen this problem before, and not all of the Tantillus parts seem to show this issue, but I won't rule out a bug with Kisslicer of course.

Which version of STL is this done off?
Sublimes blender imperial one or the copy metric SW one I did?

It looks like mine. I have never seen anything like it before and I have never used Kissslicer. If you have run it through netfabb and it still does it I would say it must be a Kissslicer issue but I can not confirm that. It does slice well with Slic3r and SF and Cura.

Yes, it's Sublime's version from git.
Cura does slice the mesh without generating the extraneous toolpaths, but it does log errors with the mesh. So I think it's just a matter of Kisslicer not handling the mesh errors in a nice fashion. Here is the Cura log:
